| Abstract: | This paper introduces the recommendation of ITU-T G.169Automatic Level Control De-vices and certain defined performance constraints.An implementation structure is proposed for the ALC system based on G.169.An algorithm for this system is also designed.The simulation experiments by means of computer show that the constructed ALC device has superior performance,and it is effective to meet the requirements in G.169. |
